Hello,

It’s anyway to detect if the user is rotating their phone (like a steering wheel) over z-axis with cocos2d-x?

I know how to calculate Pitch and Roll:

```
const double alpha = 0.5;
double fXg = 0;
double fYg = 0;
double fZg = 0;
//Low Pass Filter
fXg = pAccelerationValue->x * alpha + (fXg * (1.0 - alpha));
fYg = pAccelerationValue->y * alpha + (fYg * (1.0 - alpha));
fZg = pAccelerationValue->z * alpha + (fZg * (1.0 - alpha));
//Roll & Pitch Equations
double pitch = (atan2(-fYg, fZg) * 180.0) / M_PI;
double roll = (atan2(fXg, sqrt(fYg * fYg + fZg * fZg)) * 180.0) / M_PI;
//rotate 180 degrees
pitch=(pitch>=0)?(180-pitch):(-pitch-180);
```

But how can i calculate yaw / tilt for get the rotation?

Regards and thanks for the help!
